I feel like ads these days aren't that much useful to buy and use since only the players that have been playing for a while may know that they exist.
My suggestion is that when you buy an ad it could be shown in a chat once a while so that newcomers and people who don't know that ads exists could see other peoples ads. This would make the ads more useful and more people will use it to advertise their resources that they're selling or jobs they're doing etc and there will be some players that will write something "funny" or stupid on ads so it would be the best to avoid it somehow if possible.
Thank you for reading :)
I made a suggestion like this before, however, according to one of the admins, the issue is that some players may use it for malicious causes. And as it is atm, staff members are not always online to be able to moderate that. So it was shut down as an option to making ads more useful.
Maybe itll be considered now, but given that players have been fine without it thus far, or at minimum it's not greatly affecting gameplay. I'd say to just remove the plugin as a whole. Not that I disagree with your suggestion in making ads useful.
